Toylogic has announced its free-to-play online multiplayer game Happy Wars is now available on Xbox One.
Microsoft previously mentioned Happy Wars would be making its way to its new-gen console, due at least in part to the title being downloaded more than 10m on Xbox 360 since its launch in October 2012.
All previously released content has been packed in for Xbox One, and the version also carries split screen local multiplayer for up to four people.
Owners of the Xbox 360 release can transfer progress data to the Xbox One edition via their Live accounts, and users can participate in the same game across both platforms as well.
Here's the announcement trailer:
